Homework Help Overview

The discussion revolves around identifying the correct terminology for bending stress in a materials database. The original poster is uncertain whether bending stress corresponds to yield strength or tensile strength, and they provide details about their calculations involving bending moments and material properties.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants explore the definitions of stress versus strength, with one suggesting that bending stress may relate to maximum bending stress or tensile strength. The original poster outlines their calculations and seeks clarification on the terminology used in the database.

Discussion Status

The discussion is ongoing, with participants providing insights into the definitions of bending stress and its relation to other material properties. There is an indication that the original poster is gathering information to proceed with their calculations.

Contextual Notes

The original poster mentions a specific list of values available in the database, including Young's modulus, yield strength, and tensile strength, but does not specify which terms are used for bending stress. This may influence the clarity of the discussion.

Hello, I need to input the bending stress from a database I am not sure what name it is, would it be yield strength or tensile strength? thanks

A stress is not a strength.
Please post full details of the problem.

Hello,

I am using the engineers theory of bending M/I = E/R =o/y

I have M = bending moment 11.408 Nm
I = unknown
E= 6828*10^10 pascals
R=unknown
o=in materials database
y=perpendicular distance of a point in the beam from its neutral axis, the beam is .124m long with a vertical load from the centre so I think this value is 0.062m

So I was planning to use R=o/YR to find R

then with R I can use I=E/MR

So I believe I have all the given values I am told the bending stress is in the database that's where I am to find it, I have a list youngs modulus specific stiffness yield strength tensile strength specific strength and other values,

So I'm stuck on what the name of bending stress is meant to be in the database to continue working values out.
 
Sounds like you want the maximum bending stress the material can withstand. If the component is under tension then this would be the same as the tensile strength.
